Okay I got a couple of quotes for printing the Prusa parts as per the four plates.
One said over £600 + VAT
The other costed each plate as follows
Plate1 £391.25
Plate2 £263.92
Plate3 £286.24
Plate4 £139.34
Which I make £1080.75 + VAT
Obviously both costs were way over the top as far as I am concerned. Not surprised but was interesting to see how much more expensive than buying reprap printed parts via ebay.
